Last week, Microsoft announced the winners of its first Surface Music Kit contest, where one of the prizes was the unique hardware accessory for the company's tablets that lets people remix music tracks. This week, Microsoft continued to promote the Surface Music Kit blade in a new video and blog post.

In a post on the Surface blog, Bryson Gordon, a director on the Surface team, wrote that he took an old laptop that needed some work done to his local Microsoft Store. While at the store, he was told that one of the store's associates, Jonathan Velasquez, was a big fan of the Surface Music Kit. Gordon left his email and a few hours later he received a video from Velasquez showing what he was able to do with the accessory after hours in the Microsoft Store.

Both the contest and this newest blog post shows that Microsoft continues to promote the Surface Music Kit as an interesting add-on to its Surface. However, the only problem is that unlike the Touch and Type Cover, the company has yet to offer the Music Kit for sale. We contacted Microsoft and a spokesperson told us simply that the company does not comment on future product plans.

We are also awaiting word on the promised Power Cover for the Surface Pro tablet, which was officially announced with the new Surface tablets in September and is supposed to greatly increase their battery life. Microsoft said at that time it would be launched in early 2014 but no specific date has been revealed.
